Porto 3-1 Nacional; Tondela 2-1 Sporting

Porto secured yet another victory to extend their incredible winning run to 18 games across all competitions.

Porto had already broken their club record for most consecutive victories, which was 15 heading into the season, and they don't look ready to stop the winning feeling anytime soon.

Most recently, they secured victory over lowly Nacional, earning a 3-1 victory thanks to a brace from Brahimi and another goal from Tiquinho Soares.

Brahimi grabbed the first in the 33rd minute, squeezing the ball under the Nacional goalkeeper and into the back of the net, before Tiquinho doubled advantage 6 minutes later with a header.

It looked as if Nacional may make a game of it when they bagged a goal almost immediately, Rochez firing the ball low and into the corner to beat Casillas.

But Brahimi put the game to bed eleven minutes after the break, his powerful shot too hot to handle for Lucas Franca in goal.

The win means that Porto are now 6 points clear of second place Braga. 

Meanwhile, Sporting came away from Tondela with nothing, Keizer's men suffering a shock 2-1 defeat despite Tondela being reduced to 10 men with 40 minutes remaining.

Tondela grabbed their first after just 6 minutes, thumping the ball past Renan Ribeiro.

And that was how the score remained going into half time, Sporting unable to find a way through Tondela's resilient defence.

And, despite being reduced to 10 men after Jaquité picked up a second yellow card, it was Tondela who found the back of the net yet again, Tomane scoring a sensational trivela to curl the ball into the far corner.

Sporting did respond, Mathieu thumping the ball home on the goal line, but that was all Sporting managed, unable to pull back on level terms.

It leaves Sporting 4th in the table, 8 points off top spot.
